Now, I have two more things:
First: If you have just started implementing this with WP-Table Reloaded, I'd actually make a recommendation: Switch to the official and designated successor TablePress now ( http://wordpress.org/extend/plugins/tablepress/ ). This will save you some time when WP-Table Reloaded is being discontinued in favor of TablePress in the near future.
Secondly: I'm actually not sure that your approach is a good one. From what I can see, you want to use WP-Table Reloaded as a database system, to get data of a clearly defined type (namely information about some person). I can imagine that this would be much better suited for implementation using WordPress Custom Post Types ( http://codex.wordpress.org/Post_Types ), so maybe that's something that you should investigate. With that approach, each person would be a separate post of your new Custom Post Type.
